Question 1013016
.
You walk an average 3.2 mph on the way to school, and at an average of 4 mph on the way home. The total walking time is 18 minutes. How far away is the school?
-------------------------------------------------------------


<pre>
Let x be the unknown distance from home to school.

Then you spend {{{x/3.2}}} hours for the way from home to school.
You spend {{{x/4}}} hours for the way from school to home.
The equation is 


{{{x/3.2}}} + {{{x/4}}} = {{{18/60}}},   or

{{{x/3.2}}} + {{{x/4}}} = {{{3/10}}}.

Can you solve it yourself?
